SKSE said that I needed to update to the latest version of Skyrim, and I already had the current version(1.9 something) running. I signed up for the Beta Update, but that didn't change anything, so I unsubscribed from the Beta Update. That caused Steam to update once more. When I checked to see which version was running it said it was running a 1.8 patch. I logged out and then back into Steam, but it is still running 1.8. Any advice?

Never mind. I found this helpful page(http://steamcommunity.com/app/72850/discussions/0/810925398535156568/) and after verifying my cache it updated.
